Africa: Nile, Limpopo at risk from climate change

Climate change is likely to lead to increased average rainfall in the world's major river basins but weather patterns will be fickle and the timing of wet seasons may change, threatening farming and foodstocks, experts say. Furthermore, some river systems in Africa - southern Africa's Limpopo, north Africa's Nile and West Africa's Volta - are set to receive less rain than they do at the moment, hitting food production and fuelling international tensions.
